Maybe I'm using the wrong kind of task.
What I am trying to do is return all the features of multiple feature classes. I want the functionality of the Query Task to be able to return everything, but I also want the functionality of the Find Task to be able to search multiple layers.
When I trying only specifying layer id's, but no search attributes or search text with the Find Task, I get errors.
Is there a way to do this besides something ugly like chaining together a bunch of Query Tasks?
